A major change is that the graph will be defined for negative x when x has an even power.

Note than the graph of ln(x) is only defined for positive x as you cannot take the logarithm of a negative number. But if you have , the graph will be defined for both positive and negative x as a negative value of x will become positive once you square.

Also, the graph will become steeper, due to you taking the natural logarithm of a larger and larger number as you increase the power of x.
